In an interview earlier this week where she renounced any interest in custody, former wife Debbie Rowe revealed that the late Michael Jackson’s three children were not biologically his own. But the big shocker? They’re not biologically hers, either. Dun dun DUN! TMZ says

Debbie Rowe is not the biological mother of the two kids she bore for Michael. All three children were conceived in vitro. Debbie’s eggs were not used. She was merely the surrogate, and paid well for her services.

Well, if Michael Jackson’s not their dad, then who is? According to Us Weekly

Their biological father is Arnold Klein, Jackson’s L.A.-based dermatologist and Rowe’s former boss.

Okay, so they’re biologically Arnold Klein’s, but legally they’re still Michael’s kids, right? Um, not exactly:

Jackson never filed legal papers to adopt any of his children.

As for why Jackson didn’t formally adopt — at the time the kids were born there was no third party whom he believed would try and claim custody. For some reason, Jackson never thought [anyone] would mount a custody challenge.

In other Michael Jackson news, the drug Propofol — which is only available to medical personnel and whose sole use is to put people under anesthesia before major surgery — was discovered at the his home. TMZ says

Propofol can only be administered with an IV. Propofol [produces an intense burning sensation] and the drug Lidocaine is used to reduce the pain associated with the Propofol injection. Interestingly, Lidocaine was found near Jackson’s body [at the time of his death].

One of the major side-effects of Propofol is cardiac arrest if it’s taken in combination with narcotic painkillers; however, Propofol is so powerful it can stop someone’s heart on its own.

Sources say the drug is so inappropriate and reckless for home use, if a doctor facilitated it for Jackson, he or she could be prosecuted for manslaughter.

Stayed tuned for tomorrow’s episode of “As the Michael Jackson Turns,” in which Dr. Rip Studwell reveals that John Black is actually the real Michael Jackson but doesn’t yet know it because of a mysterious case of amnesia, and that the Michael Jackson who died was actually an evil clone engineered by Stefano DiMera in an attempt to take down the Bradys once and for all.
